Last Saturday the 23rd of October we held our community test minting event on rinkeby.cryptopia.com to test all the changes and upgrades we made to our website and smart contracts. We requested your help with that, and you did that in large numbers! Thank you!


Winners of the testing round on October 23rd

To make the testing as fun and exciting as possible for the community we reserved three NFT prizes for the community! The test went very well and the winners of the three free NFTs on the Ethereum mainnet are known!:


  • Address 0x9aEEf71169db36576230Ed6631735E3003AF48C3 minted the card with TokenID 9317, which was the card with the highest getTokenScore of 99263.
  • Address 0xe7D97Cd497700d65Fe40740ED7fAbecC4C1ca0D4 minted the first legendary card with TokenID 3432.
  • Address 0x93843c248a882d8c24DB4e9786EB1C68F0a2fF02 minted the card with TokenID 5585, which was the card with the lowest getTokenScore of 43048.


Congratulations! :) All of these addresses will receive a free NFT once the mainnet minting starts!


Final test round on Friday the 29th of October

However, based on this latest testing round, we decided to make a few more tweaks to our smart contracts and our website. And to test those, we will be doing a final testing round this Friday the 29th of October at 12PM CEST. This testing round will be similar to our latest testing round. And like last time, we want testing to be fun and exciting.

This Friday the 29th of October at 12PM CEST the new smart contracts will be put online and the counter will begin again at 0. Again, there will be three mainnet NFT prizes reserved for the addresses that:


  • Mint the card with the highest score (based on the getTokenScore function);
  • Mint the first legendary card;
  • Mint the card with the lowest score (based on the getTokenScore function).


These persons will receive a free NFT once the mainnet minting starts!

The count of the Token IDs will be set to 0 before Friday the 29th of October at 10PM CEST. From that point on, everyone is free to mint as many NFTs on the Rinkeby testnet as they want until the 10,000 NFTs are minted.


After the final Rinkeby test event is completed, we will start the countdown for mainnet minting on Monday, November 1 at 10AM CEST on cryptopia.com. The duration of the countdown isn’t known yet. It depends on any possible issues that arise and the momentum that we have on November 1.


How to participate in the final test round on October 29th

The remainder of this post will explain how you can mint Cryptopia NFTs on rinkeby.cryptopia.com. In a nutshell, the steps to do this are:


  1. Setup a MetaMask wallet and connect it to the Rinkeby testnet
  2. Get Rinkeby test ether from a rinkeby faucet
  3. Visit rinkeby.cryptopia.com and mint NFTs
  4. Report issues or bugs with the website or smart contracts (optional)

How to mint Cryptopia NFTs on the Rinkeby testnet

Step 1: Setup a MetaMask wallet and connect it to the Rinkeby test network

To interact with our smart contracts, you need to install the MetaMask browser extension or download the MetaMask mobile app. In this post, we will explain how you can install the app.


Installing Metamask

Step 1. Download and install the MetaMask app from Google Play or the App Store.


Setting up Metamask

Now that you have installed the MetaMask app, it’s time to head to MetaMask and create an account.


Step 1. Click on the “Get started” button.

Now, you will be prompted to set up a wallet through ‘Import using Secret Recovery Phrase’, ‘Sync with MetaMask extension’ or ‘Create a new wallet’.


Step 2. If this is the first time you are setting up a MetaMask account (or any other wallet), select ‘Create a new wallet’. If you have a wallet already, you can select ‘Import using Secret Recovery Phrase’ and then you will be asked to input your 12 word seed phrase to link your account.

For the remainder of this guide, we will assume this is your first time using MetaMask and that you will use the ‘Create a new wallet’ option.


Step 3. Once you’ve opted to create a new wallet, you will have to accept the terms of use.


Step 4. You will be prompted to create a new password. Enter a secure password and click ‘Create password’ to create your wallet.


Step 5. Read and watch the information provided to you by the MetaMask app and continue through the screen by clicking ‘Start’ until you have to confirm your password again. Enter your password and click the ‘Confirm’ button.


Step 6. When you arrive at the ‘Write down your Secret Recovery Phrase’ screen, click the ‘View’ button. You will see a 12 words seed phrase for your wallet. Write these down in a notebook or somewhere else where you will not misplace them. Store this somewhere safe. DO NOT store these online, as that can always be a potential security risk. Even though we are testing on the Rinkeby network, it is a best practice to store this 12 words seed phrase offline and in a secure location.


Step 7. After writing down your seed phrase, click ‘Continue’. You will now need to verify your secret phrase by selecting the previously generated phrase in order. Click ‘Complete Backup’ when finished.

Again, if you lose it, no one can help you recover the secret phrase, so it’s very important that you have it well-documented.


Using MetaMask

Congratulations! Now your MetaMask wallet is set up.

You can use your wallet to house your NFTs and other tokens, but the unique (and public) wallet address associated with your account also allows other users to send you different kinds of tokens directly to your wallet.


Your address is easy to identify. It is the 42 string character starting with ‘0x’. In the app you can copy the address to your clipboard by clicking on the address.

You can find your ethereum address here (This looks slightly different on mobile, but MetaMask doesn’t allow screenshots)

The final step. You are now in the Ethereum mainnet network. To make sure you can use it for our Rinkeby testing event, you have switch to the Rinkeby test network by clicking ‘Ethereum Mainnet’ in the app, and selecting the Rinkeby test network.


Make sure to set your wallet to the Rinkeby test network! (This looks slightly different on mobile, but MetaMask doesn’t allow screenshots)


Now your MetaMask wallet is setup correctly and good to go!


Step 2: Get Rinkeby test ether from a Rinkeby faucet

You now have your MetaMask wallet setup correctly. This means you are almost ready to start minting your NFTs on rinkeby.cryptopia.com! However, you don’t have any Rinkeby test ether yet. We will fix that by making use of a Rinkeby testnet faucet. Let’s do that!

Step 1. Create a tweet on your Twitter account that includes your Ethereum address. This tweet can contain any other information, as long as it contains your Ethereum address.

A bit of enthusiasm never hurt nobody!

Step 2. Copy the link to your tweet that contains your Ethereum address.


Step 3. Go to https://faucet.rinkeby.io/.


Step 4. Paste the link to your tweet in the input field and select one of the ‘Give me Ether’ options.

You should now receive your Rinkeby test ether on your Ethereum address. All for free! 😉

Unfortunately, we do have to mention that the Rinkeby faucet has been having some trouble lately. If this happens to you, it helps to just keep trying every now and then. Since we also run into this problem from time to time, we are unfortunately not able to provide everyone with test ether. We will try to help out as many people as possible, but our test ether is not unlimited. So best to get some yourself!

For now, we’ll assume that everything went fine!


Step 3: Visit rinkeby.cryptopia.com and mint NFTs

Ok, so you have your MetaMask wallet ready with some Rinkeby test ether in it. Cool! That means that you are ready to start minting some unique Cryptopia testnet NFTs!

Step 1. Go to rinkeby.cryptopia.com.

Step 2. Go to the mint section either by clicking on ‘Mint’ on the homescreen or navigation bar, or by scrolling down the page.


Step 3. When you arrive at the mint section, select the amount of NFTs that you want to mint and click the ‘Mint’ button.


Step 4. You will be prompted to connect your wallet through WalletConnect. Select the Mobile option and click ‘Connect’.


Step 5. You will be redirected to the MetaMask app and need to log in to the app. You will then be prompted to connect your address with rinkeby.cryptopia.com. Do this by clicking the ‘Connect’ button.


Step 6. Go back to your browser. In the upper right corner you should now see that your address is connected to rinkeby.cryptopia.com.

You might need to refresh the page and return to the mint section.


Step 7. Similar to step 3, select the amount of NFTs that you want to mint and click the ‘Mint’ button.


Step 8. You are now prompted to confirm the transaction. Do this by clicking the ‘Confirm’ button.

Congratulations! Your transaction is now mined and your NFTs are now being minted!

You are free to repeat steps 6 and 7 as many times as you wish and as the Rinkeby faucet allows! Let’s mint those 10,000 test NFTs!


Step 4: Report issues or bugs with the website or smart contracts

If any issues or bugs appear during your minting experience, we are very happy to receive feedback about it! If you find anything, please let us know through https://docs.google.com/forms/d/e/1FAIpQLSf5Qyf8IH-w7UoEuIHtgHAQcVjH_wkLHty5xCHgYnO_WZ3HzA/viewform.

Please note to always take a screenshot of the console (press F12) and attach it as an attachment if applicable.


Happy minting!

We hope you will all have fun minting as many test NFTs as you like and we hope to interact with you in our Discord channel at discord.io/cryptopia. There you can meet fellow Cryptopians, discuss your plans for Cryptopia and maybe even find a clue that helps you to solve the mystery to our 3 NFT specials!
